Abstract：
The mechanism of friction-evaporation process for target spectator contact layer in high energy nucleus-nucleus collisions is presented.The distribution of multiplicity,azimuthal and spatial angles,transverse and total momenta,as well as kinetic energy of target black fragments are calculated and compared with the experimental results of 200GeV/N ¹⁶O-Em interactions.
